Mount Vernon, NY Environmental Rules: Boat Dock Permits (2026)

F, Wetlands setbacks. The rule blocks any building or structure within that 25-foot band, but it carries a named exception for water-dependent facilities: piers, docks, marinas, and boat launching, storage, repair or service facilities may be built inside the buffer once the appropriate approving agency grants approval. The code does not fix a single body as that approving agency for every use; § 267-29 names the Planning Board as the approving agency for a specific list of special permit uses, so a dock applicant should confirm with the Building Department which board or officer reviews a particular waterfront project.

E, Land underwater, which lets an owner use filled underwater land to satisfy yard setback requirements if the Planning Board and other responsible governmental agencies approve a filling plan, so a marina or dock project that also involves filling submerged land triggers a second layer of review. Because the dimensional Schedule for each zoning district is published as a separate eCode360 attachment, this wetlands buffer works independently of, and on top of, whatever setback a district's dimensional table otherwise requires. Applicants pursuing a dock, pier, marina, or boat storage/repair facility near a wetland boundary should expect a site plan or special permit application, agency sign-off before construction, and compliance with any separate state and federal wetlands permitting requirements.
